Jesse? SALISBURY, F HAMDEN, oonnnczrr GUT, ASSIGNOR TO THE AMERICAN BUCKLE BUTTON LOOP Application filed January 25, 1930. Serial No. 423,436.

This invention relates to button loops providing means by which a strap-may be conveniently connected with and disconnected from a button carried by a garmentor the like intended to be supported by the strap.

The objects of the invention are to provlde a button loop having looped extremities relatively spaced and pivotally connectedby a toggle-jointed member the knee of which is permanently located withm the loop; to provide in connection with a button loop, togglejointed members providing a button-retaining loop normally closed and positloned be tween the arms of the button loop; to provide toggle-jointed members providing a button-retaining loop normally closed and having exterior cam-surfaces for engagement by a shank of a button to open the retainlng loop; to provide a button loop permitting the shank of a button tobe moved into and out of the retaining loop along the plane ofthe loop only upon contracting the extremities against the spring tension of the arms of the loop; and to provide folded toggle-jointed members having spaced walls enclosing the extremities of the arms of the button loop to which the members are pivoted by pivot means integral with each member.

This invention consists in the novel constructions, to be hereinafter described or claimed, for carrying out the above stated objects and such other objects as may hereinafter appear.

The invention may be characterized by reference to one illustrative device embodying the invention and illustrated by the sever al figures in the accompanying drawmgs m which the Figure 1 is a front elevation of loop illustrating the retaining loop in perspective and in normally closed position; the Figure 2 is a front elevation thereof illustrating the retaining loop in an open position; the Figure 3 is a side elevation thereof; and the Figure 1 is a group of plan and side views of a toggle member before being folded.

While the invention is not limited to any specific form of construction and the details varied tovproduce the novel features hereinafter claimed, the device is illustrated as a button loop comprising the suspension loop 1 providing the bar 2 around which may be looped a strap upon which the device is intended to depend, the button-receiving loo-p 3, and the button-retaining loop 4.. The button loop is preferably formed of a piece of resilient wire of which the middle portion is bent to form the suspension loop 1, the remaining end portions of the wire depending. from the suspension loop 1 to provide the wire side-arms 5 and 6 cooperating to form the buttonreceiving loop 3 and an associated loop, side-arms 5 and. 6 terminating in the relatively free looped extremities 7 and 8, respectively. The button-retaining loop 1 comprising the toggle-jointed members 9 and 10, is preferably made of sheet metal, each member being stamped out approximately in the form illustrated by the Figure 1 and folded upon the dotted lines 11 and 12 so that each of the members 9 and are thus provided with the walls 13 and 1 1 relatively spaced in order that between them a wire side-arm 5 or 6 may be enclosed and thus provide a button loop of the reversible-faced type of which a front elevation as illustrated by either of the Figures 1 or 2 is identical with the reversed elevation thereof. 7 The form of each member 9 and 10 includes a portion of the shank-seat 15, the cam-surface 16, and the integral sleeve 17 providing means for the pivotal mounting of the members. The members 9 and 10 are bored through the spaced walls 13 and 14:, as at18, for relative pivotal connection and through one wall, as at 19, to receive the sleeve 17 first mounted with in a looped extremity 7 or 8, the toggle-j ointed members 9 and 10 being so mounted upon the looped extremities 7 and 8 that the knee of the toggle is permanently operable within the button loop. 7

In operation, the toggle members '9 and 10, having their connecting pivotal point 18 always out of alignment with the looped extremities 7 and 8 by reason of the toggle knee 20 continuously projecting into the button loop upon the inner side of an imaginary dead cente'rline passing through the center of the looped extremities? and 8 and being the V 3 and moved along the made to forcibly thus maintained by the contracting tension of the side-arms 5 and 6, and normally providing a closed button-retaining loop 4. The shank 21 of a button received within the loop plane of the loop is engage the cam-surfaces 16 to part the members 9 and 10 and open the entrance to the retaining loop 4 whereby the members 9 and 10 are operated upon their relatively connecting pivot, as at 18, and the spaced looped extremities 7 and 8 are contracted against the tension of the resilient arms 5 and 6, as illustrated by the Figure 2, and until the shank passes into the retaining loop 4 when the resiliency of the arms 5 and 6 causes them to expand to their normal relatively spaced positions whereby the entrance to the retaining loop 4 is closed. The open position of the toggle members 9 and 10 is limited by their respective stops 22 provided by the connecting portion of the sheet metal between the folded walls 13 and 14.

I claim:

1. A button loop having depending spring arms terminating in relatively spaced extremities, and toggle-jointed members pivotally mounted upon the extremities and having a toggle-knee operable wholly within the loop.

2. A button loop having depending spring arms terminating in relatively spaced extremities, and toggle-jointed members pivotally mounted upon the extremities and having a toggle-knee operable wholly within the loop, portions of each member cooperating to provide a normally closed retaining loop positioned between the arms to hold the shank of a button.

3. A button loop having depending spring arms terminating in relatively spaced extremities, toggle-jointed members pivotally mounted upon the extremities. and having a toggleknee operable wholly within the loop, portions of each member cooperating to provide a normally closed button-retaining loop positioned between the arms, and cam-surfaces provided by the member portions for engagement by the shank of a button moved along the plane of the loop to part the members against the tension of the arms.

4:- A button loop having depending spring arms terminating in looped extremities relatively spaced, and toggle-jointed members pivotally mounted upon the extremities and having a toggle-knee operable wholly within the loop, each member comprising a sheet metal folded formation with walls relatively spaced to enclose the extremities, portions of each member cooperating to provide a normally closed button-retaining loop between the arms.

5. A button loop having depending spring arms terminating in looped extremities relatively spaced; toggle-jointed members pivotally mounted upon the extremities and having a toggle-knee operable wholly within the loop, portions of each member cooperating to provide a normally closed button-retaining loop positioned between the arms; and camsurfaces provided by the member portions for engagement by the shank of a button moved along the plane of the loop to part the members against the tension of the arms, each member comprising a sheet metal folded formation with walls relatively spaced to enclose the extremities.

6. A button loop having depending spring arms terminating in relatively spaced extremities; a button-shank retaining loop carried by the extremities, and means provided by the retaining loop to permit the shank of a button to be manually moved into and out of the retaining loop along the plane of the loop by contracting the extremities against the spring tension of the arms.
